CALIFORNIA suenen-Ron HANGER Application filed April 15 This invention relates to a device termed a sucker-rod hanger adapted to be employed in oil well drilling1 apparatus for hanging or supporting sections oit sucker rods employed in the operation oitl the wells in the well derrick.

An object of the present invention is to provide a sucker rod hanger with a hook #for supporting the hanger having a normally lo closed safety member, and an object is also to provide an additional suspendingl member for the hook adapted to automatically retract the latch :trom the hook ot the hanger to facilitate securing the hanger to a supporting means.

Another object of the present invention is to provide a form of sucker rod hanger with a plurality of `chains mounting the rod gripping clamps, the chains being mounted upon a twopart body, the lower part being adapted to act as a receiver for the chains when the hanger is not in use, and preferably constructed to serve as a chamber holding a material ttor rinsing the chains and preventing the a5 same rusting.

Various other objects and advantages of the present invention will appear from the following description oi a preferredv form of sucker rod hanger embodying the invention.

For this purpose reference is made to the accompanying drawings, in which a preferred examliile oi the sucker rod hanger is illustrated.

.ln the drawings:

Fig. 1 is a front elevation.

Fig. 2 is an elevation mainly in vertical section.

Fig. 3 is an elevation on a smaller scale of the hanger with the lower part of the body "i0 removed7 and the chains extending to operating position.

Fig. l is a front view of one of the clamping members secured to the chains, and

Fig. 5 is a view at right angles to Fig. fl.

Referring to the drawings the sucker rod hanger there illustrated comprises a main supporting member 2 preferably in the form ot an inverted hook 3 having a downwardly eXtending shank l. 5 indicates a safety latch 5U or guard normally closing the mouth of the 1925. Serial No. 23,336.

hook, the latch or guard 5 being pivoted as at G to a bracket 7 of the shank Ll oill the hoek.

8 indicates a spring normally urging the guard 5 into the closed position. The guard 5 has opposed side walls 9 extending to the 55 opposite side ot the shank l and there are secured together by a bolt 10 pivotally mounting an auxiliary supporting member' 11. This member may be of any desired shape terminating in a loop 12L as indicated 6e in lig. l, and is provided with a cani part 12 cngageable with the shank 4 when the suppleinental supporting member 11 is pivoted to the upward or supporting position. The ac tion ot this cani 12 is to pull the guard 5 into et the open position enabling the hook 3 to be readily engaged with the supporting device and locked therein by the release of the au` ili ary suspending member 11.

The main suspein'ling` member 2 addition- 7e ally supports a two-part body 12b, the upper portion 13 of which is conical in i'orni, the apex lll oi" the cone fitting the shank /l ot the member 2 and the base oil the cone being riveted to a base plate 15 having an opening 16 75 through which the shank l passes. The end of the shank 4 passing below the base plate 15 carries a nut 17 engaging the base plate for supporting the body thereon.

18 indicates a hood riveted to the conical Se part 13 of the body and angled outwardly therefrom. The hoods 18 support the upper part ot the conical body on the chain container hereafter described and prevent excessive tangling of the chains which would occur it S5 the conical body passed further into the chain container. To the lower end ot the conical body 13 is secured a number oi.' chains 19 which `at their' ends each separately support a clamping member 20. These chains and clamping` members 20 are adapted to be coiled up and carried in the lower bod y part 21 ot the hanger which is in the form o'lI a cylindrical container suitably secured to the body part 13 as by clamps 2Q. 95

The clamping members 20 each include a. main clamping part 23 having an opening at their ends by which they are secured to the chains and having a gripping curved groove 24 at their other end cooperating with the m0 grooved straight face 25 of a cooperating clamping part 26, the cooperating clamping part being pivotally secured as by a bolt 27 to the clamping part 23. Clamping members 2O in operation serve to support or suspend rods which are part of a pumping apparatus. In oil wells a well is frequently pumped by plunger pumps which may be located several thousand feet below the surface of the well and it is frequently necessary to removethe plunger and rods from the well. Vhen this is done about every thirty to sixty feet of the rod is unclamped and such a section is received by one of the clamps 20 and supported by the device of this invention. It will be readily seen that the two surfaces of the clamps provide a means for positively gripping` the rods when they are suspended on the device. r

Y1With the herein described sucker rod hanger, when the hanger is not in active use, the lower body part 21 can be lilled with a light-weight oil which will maintain the chains 19 and clamps 20 clean and in proper condition for use, and prevent their rusting. Moreover, the two-part body construction permits the sucker rod hanger to be readily transposed, despite its long depending- Y chains, in a compact space ready at all times 30 for instant use. A

In use, the hanger is hoisted to the point in vthe derrick where it is tobe suspended by a rod secured to an auxiliary suspending member 11; the raising of the hanger in this manner removes the safety guard 5 to the open position and at the arrival of the hanger at the upper end of the derricl; it may be readily suspended in its intended operating position. The member 11 -is considered as an auxiliary supporting member since this mein Aber is used to support the device, or at least the device excluding parts 21 nearest operations. VVhen the device is supported on member 11 it will be noticed that the cam 12 automatically opens the latch for hook 3. Then by a release of the member 11 the guard 5 will automatically close across the mouth of the hook 3, and vthe hanger is safely suspended-in place. Each of the clamps 2() secured to the chain 19 may then be employed to support or suspend a section of sucker rod or the like iii the well derrick, as is well understood in the art.

1While the embodiment of the invention herein described is well suited for accomplishing the purposes of the invention, it is to be understood that various modifications may be made in the details of the invention without departing from the spirit and scope there` of, and the invention is therefore of the scope of the appended claims.

I claim: Y f

1. In a device of the class described, the

combination of a safety hook, means comprising a two-part body supported by the hook for carrying a plurality of chains, the lower part of the body being detachable while in use, a rod gripping clamp mounted on the end of each chain, the lower part of said twopart body being adapted to act as a receiver for the chains when the hanger is not in use.

2. In a device of the class described, the combination of a safety hook, a two-part body supported by the hook, one part being of conical shape and adapted to support at its lower end a plurality of chains, each chain carrying a rod gripping clamp, the other part being adapted to be removably attached to the first of said parts and to provide a container in which the chains may be coiled or retained to provide a chamber for rinsing the chains and preventing their rusting.

In a device of the class described, an inverted hook member having a depending shank, a conical body through which said shank axially extends, the shank having means at its lower end for engaging and supporting said body, a plurality of chains attached to the body at circumferentially spaced apart points around its lower ends, and a rod gripping clamp secured to each chain.

4. In a device of the class described, an inverted hook member having a depending shank, a conical body through which said shank axially extends, the shank having means at its lower end for engaging and supporting said bod i, a plurality of chains attached to the body at circun'iferentially spaced apart points around its lower ends, a rod gripping clamp secured to each chain, a supplemental supporting member for the device, a latch for said hook member, a means connecting said latch with said supplemental supporting member operative to aetuate the latch to the open position upon supporting the device upon the supplemental supporting member.
